摘要

为考察神华上湾煤的直接液化性能及反应动力学，以加氢蒽油-洗油混合油作为溶剂、负载型FeOOH作为催化剂，在0.01 t·d-1煤直接液化连续实验装置上考察了不同反应温度（435~465℃）、不同停留时间（7~110 min）下液化产品组成的演变规律。研究发现，随着煤的裂解及加氢反应的进行，煤及沥青类物质（PAA）收率不断减小，重质液化产物逐步向轻质液化产物转化。当反应温度为455℃、停留时间为90 min时，煤转化率为90.41%（质量分数（，油收率为61.28%（质量分数（。随着反应条件进一步苛刻，油收率下降。基于上湾煤直接液化反应特性及其产物收率变化规律建立了11集总煤直接液化反应动力学候选模型，以BFGS优化算法对实验数据搜索、选优，确定了动力学模型参数。检验结果表明所建立的动力学模型可用于恒温阶段直接液化行为的模拟计算。

Abstract

To study the performance and reaction kinetics of direct coal liquefaction for Shenhua Shangwan coal bituminous coal

experiments were carried out in a 0.01 t·d-1 continuous tubular facility using the hydrogenated anthracene and wash oil as solvent and FeOOH as catalyst in the range of residence time 7-110 min

reaction temperature 435-465℃. The results showed that

as the coal pyrolysis and a series of hydrogenation proceed

coal and PAA yields continue to decrease

heavy liquefied product gradually transformed to light liquefied product. When the reaction temperature is 455℃

residence time of 90 min

the coal conversion reached 90.41% (mass) and oil yield 61.28% (mass) respectively

and with the reaction conditions were further harsh

the oil yield will decrease. Based on the reaction characteristics of Shenhua Shangwan coal and its data from experiments

11 lumps reaction kinetics model was build and BFGS optimization algorithm was adopted to get reaction kinetics parameters. The kinetics model better predicted the reaction behavior of direct coal liquefaction of Shangwan coal in isothermal stage.
